‡ Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The input voltage ratings may be exceeded provided the input current ratings are observed.

Description

This 8-bit universal register features multiplexed I/O ports to achieve full 8-bit data handling in a single 20-pin package. Two function-select (S0, S1) and two output-enable (OE1, OE2) inputs can be used to choose the modes of operation listed in the function table.

Synchronous parallel loading of the SN74F323 is accomplished by taking both S0 and S1 high. This places the 3-state outputs in a high-impedance state and permits data that is applied on the I/O ports to be clocked into the register. Reading out of the register can be accomplished while the outputs are enabled in any mode. Clearing occurs synchronously when the clear (CLR) input is low. Taking either OE1 or OE2 high disables the outputs but this has no effect on clearing, shifting, or storage of data.

The SN74F323 is characterized for operation from 0°C to 70°C.
